If you are using TCP then TCP will, at the protocol level resend
packets in an attempt to keep the connection alive/ or start it.

When using UDP the applicationis responsible for any reteransmissions
to handle lost packets.  I haven't looked at the OpenVPN code, but I
bet it has that functionality built.
